Reboot Command

How can I issue a reboot command to the mesa's card? any recommendations  

What are you trying to achieve? If you are trying to reboot after updating the firmware that won’t work as it requires a power cycle.

Thank you for replying, I'm actually trying to write a script to remotely reboot a CNC machine

sudo shutdown -r now

Will reboot a machine.

 

So does
sudo reboot
and both require sudo and password, otherwise they do not work.

Thank you for reminding me I forgot sudo...

On a PathPilot machine, this is not true. both sudo shutdown -r now and sudo reboot will work without being prompted for a password.

That can be setup by placing a file in /etc/sudoers.d
With Linuxcnc's raspberry pi Bookworm installer, this was the default behaviour and we removed the feature. (by deleting the user's file)

I think this link explains how to do it. But what would I know I only undid it!

This was our script to remove the file created by the default installer. 
rm -f /p2/etc/sudoers.d/010_${USERNAME}-nopasswd

That’s good to know, I will likely do that on my plasma and VMs.  Typing the password is annoying.

Thanks for the heads up Rod.
